public class PowerOnReset

extends SimObject

implements Assignable, Wakeable, Simulatable, java.io.Serializable

Constructor Detail

PowerOnReset

public PowerOnReset()

PowerOnReset(): simple constructor

PowerOnReset

public PowerOnReset(Design parent,
                    java.lang.String name)

PowerOnReset

public PowerOnReset(Design parent,
                    java.lang.String name,
                    double t_offset,
                    double t_active)

Method Detail

setSymbol

public void setSymbol(Symbol s)

Overrides:

setSymbol in class SimObject

getT_offset

public double getT_offset()

getT_active

public double getT_active()

setT_offset

public void setT_offset(double d)

setT_active

public void setT_active(double d)

setT_offset

public void setT_offset(java.lang.String s)

setT_active

public void setT_active(java.lang.String s)

parse

public double parse(java.lang.String s)

initialize

public boolean initialize(java.lang.String s)

initialize a PowerOnReset from a String, which contains the integer version id, and the offset and active times (in seconds). For example, the String '1001 0.5 0.3' specifies a PowerOnReset whose output changes from 'U' to '0' after 0.5 seconds and from '0' to '1' after 0.8 (=0.5+0.3) seconds.

Overrides:

initialize in class SimObject

write

public void write(java.io.PrintWriter ps)

Overrides:

write in class SimObject

configure

public void configure()

Description copied from class: SimObject

create and display a 'ConfigDialog' to set the parameters for a SimObject. The default ConfigDialog for the base class (SimObject) itself is empty except for the 'instance name' of the SimObject.

Overrides:

configure in class SimObject

getBindkey

public java.lang.String getBindkey()

return our bindkey as a String

Overrides:

getBindkey in class SimObject

setBindkey

public void setBindkey(java.lang.String s)

keyPressed

public void keyPressed(java.awt.event.KeyEvent evt)

Description copied from class: SimObject

react to a KeyEvent. The base SimObject ignores all KeyEvents. this method is currently only used by a few classes in hades.models.io, e.g. IpinWithBindkey.

At the moment this is actually called from KeyHandler.keyTyped(), but this naming mismatch is not considered critical...

Overrides:

keyPressed in class SimObject

mousePressed

public void mousePressed(java.awt.event.MouseEvent me)

Description copied from class: SimObject

react to a MouseEvent. The base SimObject ignores MouseEvents.

Note that the HADES schematic editor will also deliver jfig.canvas.FigCanvasEvent object, which also include the world-coordinates of the Event.

Overrides:

mousePressed in class SimObject

mouseOrKeyEvent

public void mouseOrKeyEvent(boolean shiftDown)

start or stop this PowerOnReset'erator

elaborate

public void elaborate(java.lang.Object arg)

elaborate(): This method is called by the simulation engine to initialize the simulation object.

Specified by:

elaborate in interface Simulatable

Overrides:

elaborate in class SimObject

Parameters:

arg - This parameter is ignored by PowerOnReset

evaluate

public void evaluate(java.lang.Object arg)

evaluate(): called by the simulation engine on all events that concern this object. The object is responsible for updating its internal state and for scheduling all pending output events.

Specified by:

evaluate in interface Simulatable

Overrides:

evaluate in class SimObject

Parameters:

arg - An arbitrary and unused object

wakeup

public void wakeup(java.lang.Object arg)

wakeup: this method is only used to handle "external" events on this PowerOnReset in reaction to an assign() call, which schedules a Wakeup event to update the symbol at the correct simulation time. To this end, the "arg" argument is expected to hold a WakeupEvent whose arg member is a StdLogic1164 object.

Specified by:

wakeup in interface Wakeable

schedule

public void schedule(double time,
                     StdLogic1164 value,
                     boolean interactive)

assign

public void assign(java.lang.String value,
                   double time)

specify a new output value from an external source (like a script). Calling this method will result both in the corresponding output event and an update/repaint of the PowerOneReset graphical symbol at the specified simulation time. The 'value' String is expected to have a one-character encoding of the StdLogic1164 value, namely "U" "X" "0" "1" "Z" "H" "L" "W" "D".

Internally, the latter graphical symbol update is implemented via a Wakeup event for this Ipin.

Specified by:

assign in interface Assignable

getToolTip

public java.lang.String getToolTip(java.awt.Point position,
                                   long millis)

construct a (short) tool tip message for a SimObject. This method should be overridden as needed.

Specified by:

getToolTip in interface ContextToolTip

Overrides:

getToolTip in class SimObject

toString

public java.lang.String toString()

toString() - the usual info method

Overrides:

toString in class SimObject
